in reply to Exception::Class - how to use?

Yes, that is how it works (there's no point in catching the exception inside set_number because set_number is using the exception to signal failure to calling code).

To make it a bit nicer, you could use Exception::Class::TryCatch in tandem with Exception::Class -

use Exception::Class::TryCatch; ... # try eval { $obj->some_method('foo') }; # catch if ( catch my $err ) { $err->isa('Bio::Phylo::Exceptions::BadNumber') and do { handle_this( +$err) }; $err->isa('Bio::Phylo::Exceptions::ObjectMismatch') and do { handle_ +that($err) }; }
